Parallel to Your Heart

By ilYamaTsuna7227li

Previously…

"He isn't with you?" Reborn asked. Tsuna shook his head and the baby sighed.

"Oh well. I guess I have no choice." Reborn said. "Dame-Tsuna, if by the end of class Gokudera still hasn't shown up I want you to wait for Yamamoto's baseball practice to end and go home with him instead."

…

"I'll get going then." Tsuna said as he grabbed his bag. He walked to the door his eyes shadowed. He stopped when his hand was on the door knob and he turned back. "I… I l-" Tsuna shook his head. "I'll see you tomorrow."

And with that said, the brunet stepped out into the open and closed the door behind him, leaving an unknowing sleeping prince by the bench…

Chapter 10

It was dark, in the room of a certain Sawada Tsunayoshi.

The said brunet was currently lying down in his bed with a faraway look in his eyes as the blankets covered the lower half of his body. He didn't mind the fact that his room was dark or the fact that it was so cold. He was too busy thinking about something to let anything get to him.

However…

BANG!

"HIEEE!" Tsuna sat up in shock as his door was opened harshly. His eyes widened when he saw his tutor standing by his door with a murderous aura around him.

"R-Reborn!" Tsuna said nervously. "Don't you know how to knock like a normal person?"

The tutor frowned even more and Tsuna couldn't help but gulp. Reminding the world's best hitman about his manners when he was in a bad mood was not a good move at all.

"Dame-Tsuna…" Reborn said making sure his voice was filled with suppressed anger.

"Y-Yes?" Tsuna answered nervously as he crawled back instinctively.

"Why the hell did you go home by yourself?" Reborn asked in a quiet voice. "And after I specifically told you to go home with Yamamoto…"

Tsuna raised up a defensive hand. "Ah w-well you see about t-that… Y-Yamamoto w-was a-asleep a-and I-I…"

BANG!

HIEE! Tsuna screamed in his mind as a bullet blew past him, lodging itself in the wall.

"Urusai. You're voice is irritating me." Reborn said, his eyes still shadowed by his fedora. "You're lucky that we have captured those assassins of yours before they could come and hurt you."

Tsuna gulped as he nodded fervently. There was an awkward silence. After a few seconds of maintaining his killing aura Reborn finally let it go. He sighed as he adjusted his fedora.

"Anyway if you're wondering, after we tor- I mean 'took care' of your assassins we managed to find your storm guardian." Reborn said as he looked at the brunet.

"Ah that's right! Did something happen to Gokudera-kun?" Tsuna asked worriedly.

"Nothing out of the ordinary. Bianchi just happened to be passing by when he was getting you a drink and he collapsed." Reborn shrugged, Tsuna sweat dropped.

Ah, such bad timing. Tsuna thought.

"Anyway Dame-Tsuna, don't think that you got away with ignoring my instructions." Reborn said as he frowned at the brunet, Tsuna gulped again. "But for now I'll let you deal with the repercussions of your actions before I let you deal with you punishment. Here." As Reborn said that, he threw a phone right into Tsuna's hands.

"Ah-!" Tsuna said as he caught it clumsily. "This is?"

Reborn smirked as he turned around to leave. "What? Did you think Yamamoto wouldn't notice the fact that you left him alone?" And with that, the arcobaleno walked off, leaving a flustered Tsuna.

The brunet took a deep breath before he put the phone on his ear. "H-Hello?"

"Tsuna!" Came a serious voice at the other end of the line. Tsuna inhaled sharply as his hands tightened around the phone but Yamamoto continued. "Tsuna, why didn't you wake me up before you left?"

"Y-Yamamoto…" Tsuna began uncertainly. "G-Gomen, it's just that you looked so tired and I…" Tsuna trailed off guiltily.

There was silence.

"Please don't do that again…" Came a soft voice at the other end of the phone. Tsuna's eyes widened at the tone. It was so nostalgic. "You shouldn't go off like that without telling anyone at least…" Yamamoto continued quietly.

Tsuna closed his eyes as he silently took a deep breath. His eyes opened, showing sorrow and longing. "Yeah, I know. I'm sorry."

"Tsuna…" Yamamoto called out softly and for one moment it was easy to pretend that Yamamoto felt the same way the boss felt about him. The brunet fell back onto his bed listening to the other breathing softly on the other end of the line.

"Hm?" Tsuna answered sleepily.

"Ah- well you sound sleepy… You should get to rest." Yamamoto said softly and then he added a quiet laugh. The young boss yawned as he nodded before he remembered that the swordsman won't see him nod.

"Y-Yeah, I s-should." Tsuna said as he laughed a little in embarrassment. "I'll see you tomorrow."

"See you." Yamamoto said with a smile before he hung up. Tsuna's eyes shadowed as he put down the phone. He stared blankly at hid bed sheets before yanking them from under him and enveloping himself in the warmth.

The young Vongola closed his eyes tightly as he shivered despite the warmth. Staying in this world was so…

…frustrating…

Every morning he would go to school and walk with Gokudera. Yamamoto always had baseball practice and when he doesn't he would walk with them but then Tsuna would always be walking behind the baseball star whose strides were wider and faster than his. He felt like he was always watching the other's back and he couldn't help but wish so strongly in his heart that even if it's just for a second…

Yamamoto would look back and smile at him.

That's impossible isn't it? Tsuna said to himself as he sighed and buried himself deeper in his blankets. Because really, there's nothing to like about me so I doubt Yamamoto would look at me more than a friend…

Tsuna's eyes began to grow heavy as he yawned again. A smiling image of Yamamoto awaited him in his dreams and he willingly sunk into unconsciousness.

Tsuna, I like you for the person you are on the inside.

Really Yamamoto? Tsuna thought to himself sleepily. Does that mean that no matter what world I'm in… you'll still…?

However Tsuna wasn't able to finish this thought as he drifted off to sleep. He failed to notice a small figure approaching his bed with suspicious eyes.

"You'll still what… Dame-Tsuna?" Reborn whispered as he looked at his student's sleeping figure.

The next day… It was Saturday…

"Oi Takeshi, you can take a break from helping me today." Tsuyoshi Yamamoto said to his son whom he saw unloading the delivery truck.

"Eh? What pops? Really?" Yamamoto said bewildered as he looked at the ex-Shiguren Souen Ryu successor.

"Yes really." Yamamoto's father said with an exasperated sigh. He stepped aside when his son brought in the giant frozen salmon from the truck.

"But why?" Yamamoto asked as he placed the salmon on the counter so that his dad can slice it into pieces before storing it into the freezer.

"Well, first of all we don't have that many customers today. Second I'm giving you this free day as a reward for winning your last tournament!" Tsuyoshi said as he gave his son an approving thumbs up.

"Ahaha! That's so cool!" Yamamoto said as he grinned at his dad. He took off his apron and washed his hands. He rushed up to his bedroom and took a shower before taking his baseball bat, ball, and mitten then rushing downstairs.

"THANKS AGAIN DAD!" Yamamoto shouted as he ran outside.

"Sure, sure… Have fun!" Tsuyoshi called out to his son. When the younger Yamamoto was gone Reborn suddenly popped out from behind the counter.

"Thanks for doing this Yamamoto-san." Reborn said as he tilted his fedora mysteriously. The older Yamamoto ran a hand through his hair before sighing. "Sorry for the trouble."

"It was no trouble." Tsuyoshi said quietly as he and Reborn continued to look at the shop's entrance where Yamamoto exited.

"So the high-priced Salmon from Hong Kong…?"

"Got it right here."

"Ahaha! Today's such a nice day! Good thing dad let me have a day off!" Yamamoto said with a wide smile as he looked around at the park. Suddenly his eye brightened when he saw a good pot for baseball. "That looks like a good spot I think I'll-"

"Ah be careful-!" Came a familiar voice. Automatically Yamamoto turned to look at where the voice came from and his amber eyes twinkled happily when he saw a familiar brunet and Italian with Lambo and I-pin.

"Wah! This is so boring!" Lambo cried as he rubbed his eyes. The rain guardian saw Tsuna sweat drop as the brunet kneeled so that he could be on eye-level with the cow child.

"Stupid cow! Don't act so lazy in front of jyuudiaime!" Gokudera said about to hit him but thankfully Tsuna stopped him.

"Don't say that the game's boring just because you can't do it well Lambo." Tsuna said as he patted the Bovino. Yamamoto's eyebrow rose when he saw some bats, a few balls, and some mittens scattered on the ground. Were Tsuna, Gokudera, and the kids playing baseball?

"Tsuna-san! Tsuna-san! Is I-pin doing it right?" The Chinese child asked the Vongola. Gokudera and Tsuna turned to look at her.

"Ah, you're form is a bit off I-pin…" Tsuna said as he gently took the bat from the girl. The brunet straightened up and to Yamamoto and Gokudera's astonishment he did a good baseball form.

"Like this…!" Tsuna said as he effortlessly swung the bat and then smiled. "…see?"

"Tsuna-san is really good!" I-pin clapped and Lambo pouted.

"As expected of jyuudaime!" Gokudera said with twinkling and admiring eyes, Tsuna blushed a bit at the compliment. However Yamamoto could see the suspicions behind the eyes of the bomber as well.

"Dame-Tsuna! Teach Lambo-san how to do that!" The Lightning guardian whined. A vein-popped on Gokudera's forehead and he was about to say something but Tsuna stopped him again.s

"Hai… hai…" Tsuna said as he patted the other. "But you have to be patient, got it Lambo?" Tsuna smiled. (Jyuudaime is too kind. Gokudera thought with admiration.)

"Whatever!" Lambo said but that was as good as a yes to Tsuna.

"Neh Tsuna-san… how did Tsuna-san get so good at baseball?" I-pin asked the Vongola.

"I don't want to be prying jyuudaime… but I'm curious as well." Gokudera asked guiltily.

"E-Eh?" Tsuna said as he looked up a startled. He saw Gokudera, Lambo and I-pin looking at him expectantly. He sweat dropped a bit as he looked at the bat in his hand.

Tsuna's eyes turned a bit sad as he closed his eyes in remembrance.

"And you swing it like this…!" Yamamoto said as he showed Tsuna.

"Wow Yamamoto!" Tsuna said as he clapped happily. "That was great. I may not know much about baseball but I'm pretty sure that that swing was good!"

"Ahaha! Thanks Tsuna! That means a lot coming from you!" Yamamoto said as he approached the brunet and encircled him in his arms. Tsuna blushed but then smiled happily.

"I wish I was as good as you in sports." Tsuna said as he looked into the amber eyes of his rain guardian.

"I'm sure you'll do even better than me with enough practice." Yamamoto said confidently before he grinned. "Want me to teach you?"

"You don't have to." Tsuna sighed. "I'm a really slow learner."

"Maa… Tsuna don't be like that." Yamamoto said with a reassuring smile. "I'm sure that since it's you, you'll probably learn this stuff in no time…"

And so…

"Tsuna, your stance need to be firmer." Yamamoto said as he came up from behind the brunet and held the other steady. Tsuna blushed as he felt Yamamoto's arms around him, taking control of his shaking arms so that he can hit better.

"And…! Swing!" Yamamoto said and the two of them swung. However Tsuna lost his footing and stumbled backwards.

"Whoah!" Yamamoto said as he steadied the brunet. However he too fell back and it ended up with him on top of the boss.

The two of them looked at into each other's eyes before they bursted out laughing. Tsuna placed his arms around Yamamoto's neck while Yamamoto pulled the other closer as they laughed.

"Saa… let's try again?" Yamamoto said as he helped the other up. He gave the brunet a bright smile and Tsuna smiled back.

"Yeah…"

Tsuna opened his eyes as he held up his bat. Gokudera and Yamamoto (still unseen by Tsuna) looked at him curiously.

You stand like this Tsuna and grip the bat tight okay? We don't want it flying out your grasp now do we? Ahaha!

Tsuna smiled when he remembered Yamamoto's sound-effect teaching style. Thankfully he added a few words that he could understand now and then.

…That's when you swing with all your might Tsuna! Don't let the balls through! Whoosh! There it goes!

Ahaha! You did it!

Good job Tsuna!

The brunet held the bat to his forehead as he smiled happily while blushing. "Someone… very important taught it to me!"

Gokudera's jaw dropped as he tried to process what Tsuna said and the meaning behind his words. I-pin and Lambo exchanged looks before they shrugged. Meanwhile, Yamamoto was staring at the expression on Tsuna's face, bewildered.

Tsuna sighed as he put down the bat. Now was not the time to get mixed up in his memories with Yamamoto. Reborn told him to play with the kids so that they wouldn't blow up the house and he will play with them if it meant that his home will be spared!

Although… He didn't know what Reborn was planning when the arcobaleno gave him these baseball stuff to play with.

He must be planning something again. Tsuna thought suspiciously, however the brunet was snapped out of his thinking when he saw someone familiar looking at them not far.

"Y-Yamamoto!" Tsuna called out as he waved. Gokudera snapped out of his traumatic thoughts when he heard the name of his right-hand-man rival.

"Oi! Baseball idiot! Why are you just standing there?" Gokudera said when he turned to look at Yamamoto as well.

"Ahaha! W-Well…" Yamamoto said uneasily as he looked at Tsuna who looked back at him curiously. The rain guardian avoided the other's eye contact and laughed again. "I-I just wanted to see what you guys were up t-to! I-I see you're playing b-baseball! Can I join?"

"Tch." Gokudera said as he crossed his arms. "Who said that you couldn't?"

"The more people, the happier!" I-pin agreed.

"Lambo-san is bored." Lambo said as he picked his nose.

"Of course you can join us Yamamoto." Tsuna said as he smiled before handing over a bat to his rain guardian. "Here."

Yamamoto looked at Tsuna before he grinned uneasily. "Thanks."

Tsuna smiled back at him brightly. "No problem." Tsuna said before he turned around and dropped his smile. However…

"Tsuna, wait." Yamamoto said as he grabbed the brunet by the arm. The Vongola turned to him in surprise.

"E-Eh? W-What?" Tsuna said as he looked at the swordsman.

"Oi! Baseball idiot, what the heck are you doing?" Gokudera demanded as he approached the two.

Yamamoto's eyes widened, as though he just realized what he did and he abruptly let go. He laughed sheepishly to cover up his surprise. "A-Ah sorry about that Tsuna! I don't know what came over me!"

"A mere sorry is not enough! Kneel down to jyuudaime and-!" Gokudera protested.

"Gokudera-kun it's fine." Tsuna said to the storm guardian before he looked at Yamamoto. "Yamamoto you don't have to apologize for that." Tsuna said to the rain guardian. "It seemed like you wanted to say something important…"

"Ah well… Yeah maybe…" Yamamoto said as he scratched his cheek. "I… I don't know…"

Tsuna and Gokudera anime-fell while Yamamoto just laughed.

"A-Anyway, let's just go back to the game." Tsuna said as he looked at the two kids. "Lambo! I-pin! Yamamoto's here to help teach you some good moves!"

"YEHEY!" Lambo and I-pin cheered as they ran around happily.

Tsuna smiled as he ushered the two kids to help him pick up the balls so they can start, leaving Gokudera and Yamamoto alone.

"Yamamoto…" Gokudera said seriously. "Reborn-san called for a meeting today."

Yamamoto blinked in surprise. "Is that why my dad-?"

"Probably." Gokudera grunted. "He didn't tell me the details but I'm sure that it's about jyuudaime."

Tsuna… Yamamoto thought. "When?"

"Later, when jyuudaime takes the kids to the amusement park. Aneki will pick us up." Gokudera said as he watched his boss play with the kids.

"Who else will be there?" Yamamoto asked.

"From what I heard… Turf-top, his sister, and that annoying Kurokawa-girl will be there." Gokudera said and Yamamoto turned to him in surprise.

"Wha-? Kurokawa-san and Sempai's sister too?" Yamamoto asked, surprised.

"I said that didn't I?" Gokudera said with a frown. "Anyway, it must be serious if Reborn-san's calling a meeting for it. You should get ready for anything."

Yamamoto looked at Tsuna who was happily picking up the balls with the kids.

Tsuna, are you hiding a secret from us?

At that exact moment, Tsuna looked up and gave Yamamoto a bright smile. The baseball idol was taken aback slightly.

What did those smiles mean?

"Neh, Bakadera! Are you coming or not?" Lambo shouted out tauntingly.

"Why you stupid cow-!" Gokudera shouted.

"Lambo! It not nice to call Gokudera-san 'baka'!" I-pin scolded.

"Ahaha! Maa… maa… Let's just start playing!" Yamamoto said soothingly as he dragged Gokudera to join Tsuna and the others. Tsuna nodded in approval as he turned his back momentarily and looked at a nearby tree with a serious look.

It won't be long now… Tsuna thought as he looked down and went back to picking up the balls. Reborn is after all the greatest hitman, he surely has noticed something by now… right?

Meanwhile…

Reborn who was hidden by a tree branch looked at his student suspiciously. Ever since the day at the park, his student has been acting strange and distant most especially to the rain guardian. As his stupid student's tutor, it was up to him to get to the bottom of this.

Dame-Tsuna… Reborn thought as his eyes narrowed when his student glanced at the tree he was hiding. What are you hiding?

Author's note: If you're wondering how Reborn knew what Tsuna was thinking at the first part, well Tsuna was kinda whispering it, and Reborn just happened to be there and ahaha!Thank you for your support! Please read and review! I hope my head stops pounding soon!
